MPC82XX and SATA hardisk performance.

[leo]

Hi all,
	I use the PCI bus and PCI-SATA bridge SII3112 to expand two SATA port, my MPC8250 work frequency is CORE/CPM/BUS 200/133/66M, filesystem use ext2 under linux, i write a program to test the maxmium written speed, the result is about 60MBps/S, maybe it's too slow?  Anyone who has experience can give me some advice? How can I increase the written speed?

Best Regards!

Leo.
